Converting JSON to XML for Legacy Systems and APIs
XML remains prevalent in enterprise systems, SOAP web services, Android resources, and many configuration formats. When modern APIs return JSON but downstream systems expect XML, a reliable converter is essential. This tool maps JSON's data model to equivalent XML structure.
The conversion follows these rules: JSON objects become XML elements with child elements for each key-value pair. JSON arrays become repeated elements sharing the same parent tag. Primitive values (strings, numbers, booleans) become element text content. The result is wrapped in a root element unless the JSON already has a single top-level key.
Note that JSON and XML have different expressive capabilities. XML supports attributes, namespaces, processing instructions, and mixed content that JSON cannot represent. This converter handles the common use case of converting JSON data structures to equivalent XML tree structures, which covers the vast majority of practical conversion needs.
